1. Compound Sentences

2. What you need to know…
Compound sentences are made when two or more simple sentences (a.k.a. independent clauses) are combined with a comma and a coordinating conjunction.
Coordinating conjunctions are FANBOYS
Compound sentence formula:
Sentence + , + one of the FANBOYS + sentence + . = compound sentence

3. Don’t misunderstand…
Not every sentence with a FANBOY word is a compound sentence!
Not every sentence with a comma is a compound sentence!
Compound sentence CAN be combined with other sentence forms (example: adding a modifier)

4. Say What?!
In Chemistry you learn that a compound is made from combining two or more different things. Same with compound sentences.

10. Another Option
Compound sentences can also be formed by joining two related sentences with a semicolon. (No need for a FANBOY here. The semicolon joins alone.)
The separation is more subtle; sometimes we want less separation between sentences.

11. The semicolon
Links two or more independent clauses with similar ideas.
Between the period and the comma lies the semicolon.
Stronger than a comma, weaker than a period
The part of the sentences after the semicolon is not capitalized unless it is a proper noun.

12. A few semicolon examples…
Harry was sure he would not be able to fall asleep; the evening had been so packed with things to think about that he fully expected to lie away for hours mulling it all over.
